we and other people on the spf mailing list are publishing spf records

the exim acl that you could download from spf webpage is outdated and does
not work with the new draft specs, as soon as the new exim acl is available
i will post it to this list too. By now using spf filtering should be
considered experimental both because the number of domains publishing spf
records and the fact that it's not fully finished (spec changes could
happen anytime)

Best regards ...
If at first you DO succeed, try not to look astonished!
